Abstract

The lemon juice anchored polyaniline nanoparticles were synthesized using aniline as a monomer and lemon juice as acid dopant with potassium persulfate as the oxidant. The synthesized nanoparticles were characterized by XRD, FESEM and EDX. The XRD pattern of polyaniline-lemon juice has been shown crystalline nature and the average size found to be 2.998 nm. The polyaniline-lemon juice nanoparticles were immobilized on column silica by grinding method. The polyaniline-lemon juice@silica nanocomposite were characterized by XRD and FESEM. The XRD pattern of polyaniline-lemon juice@silica nanocomposite has been shown amphorous nature. This study has explored the catalytic application of these nanocomposites in the synthesis of various β-amino ketones via a one-pot three-component Mannich reaction of aldehydes, ketones and aromatic amines. This method provides a novel and enhanced amendment of three-component Mannich reaction in terms of mild reaction conditions and clean reaction profiles, using a small quantity of catalyst and simple workup procedure.
